@Razvan My issue with karma is actually not specific to demons, it is just exemplified by them. If the whole game makes it super easy to go negative, but hard to go positive, how many people do you think will drift negative unintentionally and then struggle to get back? The game sort of naturally pushes you that way because that's how the mechanics seem to be balanced.
As for angel, I kind of understand it. It's nice for people to have options, it's just weird to me that the options are so imbalanced.
That's a good point about PVe on the beast world, though I'm mostly listing hard mechanics so i'm not sure if something meta like that really hits the list. I will have to consider it.
